| Abstract: | Crystallisation of benzene-1,2,4,5-tetracarboxylic acid or benzene-1,2,4-tricarboxylic acid with divalent metal ions of Co, and Mn with 1,10-phenanthroline gives two new coordination solids, Co2(C10H2O8)(C12H8N2)2(H2O)6]·2H2O (1) and Mn3(C9H3O6)2(C12H8N2)2(H2O)2] n (2). The three-dimensional supramolecular structure of compound 1 is constructed from discrete Co2(C10H2O8)(C12H8N2)2(OH2)6] dimers and isolated water molecules via interesting hydrogen-bonding and π–π stacking interactions. Compound 2 has an unusual (4,?6) network, and the network is furthermore extended into a three-dimensional supramolecular architecture by the aid of hydrogen bonding and π–π stacking interactions. |
